My gearbox is leaking and I need to replace the gaskets in it. Ive not taken it out yet, but was wondering whether I will need any special tools of pullers to remove the casing? Can anyone help? Its a 5 speed box from 1985 Xr3i engine. Cheers

 

the cork gasket at the end is piss ease to change, the other place they leak from is the driveshaft seals but not as comon, the only other gasket is for the 5th gear casing to the main gearbox,,,,, but thats a pro job to do as you need to take off 5th gear and also getting it back together you have to line up the selection forks or it wont work

most comon leak though is from the end cap with a 3 quid gasket thats made of cork

There's no reason why it cant be done at home but you will need to take it somewhere to get the fifth gear removed as it requires a decent hydraulic press ot get it off. To replace the gear I bung it in the oven and it slips straight back on!

Never had a problem with selector forks?

 

its the reverse pin thingy ive had a issue with before, never lined up proper

ive done a few of em, dont need a hydraulic press to take off 5th gear but do need a puller

thats if its leaking from the case though and not the end plate

 

just had a propa look today n its the offside diff seal leaking. should be a straight forward job to do. Glad it aint the gearbox! cheers for your help tho
